To all whom t may concern.'

Be it known that I, ARTHUR A. AUsT, a citizen of the United States, residing at Columbus, inthe county of Franklin and State of Ohio, have invented certain new and useful Improvements in Windmills, of which the following is a specification;

The present invention is directed to improvements in wind mills.. The primary objectof the invention is to provide a wind mill so constructed that the vanes thereof will be disposed vertically and so mounted that the position Vthereof will be automatically shifted when the wind reaches an abnormal velocity, thereby eliminating the possibility of injury to the apparatus.

A further object of the invention is` to provide means whereby the frame supporting the' vanes will be permitted tov travel in a circle so as to assure that the vanes will be Vsuccessively positioned y,to be effectively acted upon by the wind. I

Vith these and other objects in view, as will appear as the description proceeds,.the invention consists in the novel features of construction, combinations of elements and arrangements of parts, and hereinafter to be 4fully described and pointed vout in thel appended claims.`

ln the accompanying drawing: Figure 1 is a front elevation of the device, Figure 2v is a vertical sectional view through the two wind mill units,

Figure 3 is a top plan view,.v Figure'4 is a detail sectional view through the gearing of one of the units, Figure 5 Vis 'a detail sectional governor actuated mechanism,

lFigure 6 is a transverse sectional view through one of the vanes,

Figure 7 is a sectional of Figure 2, and

Figure 8 is a horizontal sectional view through a modified form of the invention.- Referring to the drawings 1 designates a foundation, preferably cement and upon view of the view on line 7 7 which is suitably mounted a circular. track 2. Fixed centrally in the foundation is a vertical anchor shaft 3 to which is pivotally connected one corner of the substantially triangular shaped frame 4 which has the same shape as the supplemental frame 5, the latter being comparatively small and spaced vertically from the former. These frames are braced by connecting bars 6 and 7 or in any other desired manner. The frame 4 is provided with .suitable lbearings 8 for supporting the horizontal driving shaft 9, the

purpose of which will appear later.

' A pair of wind mill units 10 are employed and comprise a gear wheel 11 which has its hub 12 loosely engaged with the vertical main .shaft 13, the upper end of which is j'ournaled in the frame 5 while thelowery end of said shaft is journaled in abearing 14 of the frame 4. .p n

Upper and lower spider frames 15 areineluded in each unit 10, said frames having theirrrims 16 preferably hexagonal in contour and have their hubs 17 fixed to the shaft 13. Each rim 16 is provided; with equally spaced bearings 18, six in number, a bearing' being located atv each point of angularity of the respective rims. |The vertically disposed vanes 19 are preferably ofthe shape shown in Figure 6 of the drawings and may be formed of any suitable material, andassociated with each vane is a tube 20, the ends of which :extend for a short distance beyond the respective ends of said vanes.k The upper extended ends of the tubes 20 are journaled in the bearings 18 of the rim of the upper. frame 15 while the lower ends thereof have slidablyy and rotatably engaged therein stub shafts 21 which engage the bearing 18 of the lower frame 15, there being gears 22 fixed tothe lower ends of said 'stub shafts which mesh-with the i gear wheel 11; The stub shafts-21 are provided with pins 23 adapted to ride in the obliquely disposed slots 24 formedin the lower ends lofsaid tubes, the purpose of which will later appear. 1 f l rlhe hub 12 of ,the Ygear wheel 11y has fixed thereto a gear 25 which meshes with the gear 26 fixed tothe upper end of the shaft 27 journaled in the frame 4, there being a gear 28 fixed 'to the lower end Vof said shaft. The gears 28 mesh with gears 29 fixed to the lower ends of the shafts 13 and also fixed to said shafts are beveled gears 30. gears 30 mesh with similar gears 31 fixed to the ends of the transverse shaft 32 which is journaled in bearings 33 carried by the frame 4. Fixed centrally to the shaft 32 is a beveled gear 34 which meshes with a similar gear 35 fixed to the adjacent end of the shaft 9, the other end of said shaft having a beveled gear 36 fixed thereon which meshes with a similar gear 37 which has associated therewith a beveled gear 38. The gear 38 meshes with a beveled gear 39 upon the ad- The l jacent end of the driven or power shaft l which may be coupled in any suitable manner to the device to be operated, such for instance as a pump.

It is desired to adjust the vanes 1S) to positions to oll'er as little resistance to the wind as possible should the velocity thereo'l" obtain abnormal proportions and in order to accomplish this a centrifugal governor stl of any well known type is employed, said governor being suitably mounted on a cross bar 42, carried on the frame fl, said governor having its sha'l't ell provided with a beveled gear L -l which meshes with a similar gear @t5 lixed to the shalt 9. This governor controls the operation oi' the rod :to which has its upper end pivotally connected with the inner end of a lever et?, said lever being pivot-ally connected intermediate its ends to a bracket d8 carried by the iframe 5. To simultaneously lii't the vanos l) each. unit l() has associated therewith substantially annular trames att) which include spokes anda central hub 5() slidable on the shafts i3, said hubs having swivelly connected thereto the ends of the cross bar 5l, said cross bar beingslr pivotally connected with the lever a7 through the `medium of the yoke 52.

It will be apparent that as the wind passes between and through the units Il() that the vanes 19 will be successively positioned to be acted upon thereby, owing to the `tact that as the units rotate said vanes will be positively positioned for action upon by the wind by the gears 22 and ll. Then the velocity ot the wind becomes abnormal and the shafts 32 and 9 rotate at such speed as to cause `the governor -ll to operate to elevate the cross bar 5l and thus the tubes 20, which support the vanos 19. Owing to the presence ojtf the pins Q3 and slots Pfl the tubes will be given a partial rotationso as to bringr the respective vanos with their edges into the wind, thereby' reducing, r the speed of the units to prevent injury to the apparatus. It will be ot' course obvious that these tubes can be elevated manually upon pulling downwardly upon the rod 46 and anchoring the same, whereby the speed of the apparatus may be readily controlled and regulated.

In the modified form of the invention as shown in Figure 8, in lieu of the gears 22 and gear 11 sprockets 53 are employed and have trained therearound a sprocket chain 5ft. This sprocket chain is also trained around a sprocket which is fixed with a gear 5G, said gear being in mesh with a gear 5T suitably Afixed upon the lower frame 4.

that is claimed is:

1. A wind motor comprising a vertical support, a pair ol upper and lower radial lranies connected with said support and rotatable in a horizontal plane axially with respect thereto, and a Jair 0i' wind mill units including` vertically cisposed vanes mounted for rotation about vertical axes and positioned between said frames.

2. In a wind motor, a vertical support, horizontally disposed vertically spaced :trames exeuding` radially from said support, an arcuate trackway for supporting said trames and to permit of their axial adjustment relative, to said support, a pair of wind mill units mounted :tor rotation about vertical axes carried by the outer ends Ot' said trames, each of said units consisting` of a plurality of vertically disposed vanes, and motion transmitting appliances connected with said vanes.

In a wind mill, an arcuately adjustable supporting t ame, supplemental trames carried in connection with said first-named frame, vanos carried by said supplemental iframes and rotatable about vertical axes, a driven member, motion transmitting appliances between said vanes and said driven member, and a governor mechanism operable autonnitically to adjust the working positions oi said vanes in accordance with predetermined wind velocities.
